Abstract
We have fabricated ordinary fired (OF) and grain oriented Bi3.15Nd0.85Ti3O12 (HF[⊥], HF[//]) samples by a hot-forging technique. The grain orientation factor F calculated from X-ray diffraction patterns of the c-axis oriented Bi3.15Nd0.85Ti3O12-HF[//] sample is determined to be above 90%. The dielectric and ferroelectric properties of Bi3.15Nd0.85Ti3O12 ceramics with different grain orientation have been investigated as a function of temperature. The a-b axis oriented Bi3.15Nd0.85Ti3O12-HF[⊥] sample had an enhanced dielectric constant (1163 at T c) and ferroelectric properties (P r ∼ 32 μC/cm2). The electrical conductivity of BNT ceramic has been studied as a function of temperature in order to investigate the conduction mechanism with different grain orientations.
